CVE-2026-106108 · Severity: medium · CVSS 4 · Published 2026-10-13

Quasar Framework's static site generation (SSG) builder can be tricked into writing HTML files outside the intended output directory when custom page paths are supplied. An attacker who can influence how pages are defined during the build process could create files on the filesystem with the permissions of the build user, potentially compromising the build integrity or system security.

Technologies: [@quasar/app-vite (npm)](https://junglewise.ai/threats/technologies/npm-quasar-app-vite). Vendors: [npm](https://junglewise.ai/threats/vendors/npm).

  ```


## Technical details

The vulnerability is a path traversal flaw (CWE-22) in the SSG build process where page definitions provide custom `dir` and `filename` values. The builder fails to validate that resolved paths remain within `build.distDir`, allowing parent-directory traversal sequences (e.g., `../`) and symlink-based redirection to escape the output tree. Exploitation requires the ability to influence SSG page definitions, which becomes practical when external or untrusted content feeds into configuration.
